Refractory gunning castable (tseem tau tsim los ua cov phom refractory sib xyaw lossis pneumatic shotcreting castable) yog ib qho tshwj xeeb monolithic refractory xa los ntawm high-pressure pneumatic xa tshuab los kho, rov tsim kho, lossis tiv thaiv cov khoom siv thermal hauv ob sab phlu yam tsis muaj kev tsim ntau. Formulated los ntawm cov qhab-nees refractory aggregates (bauxite, corundum, silicon carbide, los yog tuag burned magnesia), advanced ultrafine binders, thiab proprietary chaw activators, gunning castables npog ob qho tib si aluminosilicate qib (xws li Topower HCA-140} mus rau {41% Al2} thiab yooj yim Magnesite-raws li kev sib xyaw. Lawv ua tiav sai nyob rau hauv-situ adhesion ntawm kub los yog txias rauv substrates, ua hauj lwm ntseeg siab nyob rau hauv ua hauj lwm kub ntawm 1400℃mus rau 1800 degree. Los ntawm optimizing particle grading thiab tshuaj binders, niaj hnub phom formulations txwv aggregate rebound poob rau ntawm 8% thiab 15% - ib tug tseem ceeb heev pib rau kev tswj nqi nyob rau hauv industrial ua hauj lwm. Cov phom castables muab cov kev pabcuam thaum muaj xwm txheej ceev rau lub tshuab hluav taws xob kub kub blast mains, steelmaking converters (BOF), ladles, cement rotary kiln hoods, thiab petrochemical cracking boilers.
Tswj pneumatic nozzle siab, aggregate noo noo ratios, thiab nyob rau hauv-situ thermal curing chemistry tswj kev ua tau zoo hauv ob sab phlu adhesion thaum muaj xwm ceev kho qhov cub.

Thaum anchoring gunning txheej ntawm ntsug rauv plhaub, engineering crews nruab metallic refractory anchors xws li tshav kub-resistant.stainless hlau thauj tog rau nkojsystems nrog rau cov txheej txheem brickwork sivalumina silica refractory cib.
Engineering Mechanics: Yuav ua li cas kom txo qis tag nrho rov qab poob
Rebound poob sawv cev rau feem pua ntawm cov phom sib sau ua ke uas tawm ntawm lub hom phiaj ntawm phab ntsa es tsis ua raws li lub cev ntom ntom monolithic. High rebound pov tseg cov ntaub ntawv thiab hloov cov tshuaj sib piv ntawm cov ntsia hauv ob sab phlu:
Nruam Grain Size Distribution:Topower gunning castables feature optimized granulometry ntawm 0 thiab 5 hli. Coarse grains (3 mus rau 5 mm) muab cov txheej txheem pob txha ntom ntom, thaum cov nplej nruab nrab (0.5 mus rau 2 hli) thiab micro-fine reactive hmoov (< 0.074 mm) create a cohesive capillary matrix. Without sufficient ultrafine fines, coarse particles rebound violently upon impact.
Dynamic Water Ring Mixing ntawm Nozzle:Hauv kev teeb tsa rab phom qhuav, cov khoom siv ziab qhuav txav los ntawm lub hose, sib tov nrog dej hauv ib lub nplhaib tshwj xeeb ntau lub qhov dej nyob ntawm 0.5 meters ua ntej lub nozzle tawm. Dej siab yuav tsum nyob twj ywm nruj me ntsis 0.15 txog 0.20 MPa siab dua cov khoom siv cua siab (feem ntau 0.40 mus rau 0.55 MPa) kom paub tseeb tias tam sim no, cov ntaub ntub dej.
Nozzle Operator Dynamics (Nyob deb thiab lub kaum sab xis):Lub rab phom nozzle yuav tsum tau tuav nruj nreem perpendicular (90℃kaum sab xis) rau lub hom phiaj phab ntsa. Tilting lub nozzle rau 60℃nce rov poob los ntawm 10% mus rau ntau tshaj 30%. Qhov zoo tshaj plaws nozzle nrug yog 0.8 mus rau 1.2 meters. Tuav lub nozzle ze dhau ua rau lub siab tshaj tawm huab cua scour, thaum sawv deb dhau los txo cov kinetic compaction.
Kub Kho Technology vs Cold Turnaround Installation
Cov neeg ua hauj lwm hauv cub tawg sib npaug quotas ntau lawm tiv thaiv refractory relining ncua sij hawm. Gunning castables yog tsim rau ob lub qhov rais ua haujlwm sib txawv:
1. Kev Kho Mob Kub Kub Kub Kub Kub (600℃txog 1200 degree)
Txoj Kev Sib Tw:Txau cov dej-cov kabmob refractories mus rau lub cub tawg ci ntsa iab ua rau muaj kev pheej hmoo nrawm nrawm, tawg tawg, thiab tsis muaj zog adhesion.
Kev daws teeb meem:Cov phom kub tshwj xeeb sib xyaw ua ke nrog cov organic micro-fibers (0.05% mus rau 0.10%) thiab tshuaj binders (sodium silicate, aluminium dihydrogen phosphate). Fibers hlawv tawm ntawm 150℃mus rau 200 degree, qhib microscopic degassing channel uas tso tawm cov dej nyab xeeb. Cov tshuaj binders hnov mob tam sim ntawd nrog cov cua sov seem kom fuse cov phom phom ncaj qha mus rau cov cib ci ntsa iab hauv feeb.
2. Txias Teem Sij Hawm Saib Xyuas Relining
Txheej txheem:Thaum lub sij hawm npaj cog overhals, pneumatic rab phom tshem tawm kev ua haujlwm thiab kev siv cov ntoo formwork. Cov kav dej loj loj, cov ducting hoods, thiab cov kab mob sib kis tau raug tua tsis tu ncua ntawm tus nqi ntawm 2 mus rau 4 metric tons hauv ib teev, ua raws li kev tswj hwm dej 24-teev.
Thaum hloov los ntawm phom kho thaj tsam rov qab mus rau qhov chaw casting, cov tswj xyuas kev sib koom ua ke nrog ntom ntommonolithic refractory catsablethiab tsawg porosityqis cement castable.
Dry Gunning vs. Wet Shotcreting: Txheej txheem sib piv
Cov pab pawg muab khoom lag luam xaiv cov tshuab kev teeb tsa raws li qhov project nplai, muaj huab cua siab, thiab kev txwv tsis pub nkag:
| Kev ua haujlwm Parameter | Qhuav Pneumatic Phom Phom | Wet Shotcreting (Wet Gunning) |
|---|---|---|

| Machinery Kev nqis peev | Compact, portable pneumatic phom phom lauj kaub | Heavy piston twj tso kua mis + cua compressor teeb |
| Daim ntawv thov zoo tshaj plaws | Kub cua sov kho, confined ducting | Loj-scale txias relining (cement kilns, stacks) |
Vim li cas Qhov Chaw Refractory Gunning Castable los ntawm Tuam Tshoj?
Kev yuav cov phom monolithic castables los ntawm cov chaw tsim khoom hauv Suav teb muab cov nqi ntau, ntim, thiab kev kho kom zoo rau cov nroj tsuag txawv teb chaws:
Integrated Bauxite & Magnesite Mineral Reserves:Tuam Tshoj tuav cov thawj coj thoob ntiaj teb hauv cov khoom siv raw refractory. Topower qhov chaw calcined bauxite clinkers (Al2O3 75% mus rau 88%) thiab tuag burned magnesite (MgO 90% mus rau 98%) ncaj qha los ntawm domestic kilns, tshem tawm cov neeg nruab nrab raw khoom surcharges.
Custom Additive Formulations for Overseas Climates:Cov phom sib tov xa tawm mus rau thaj chaw kub thiab txias (Southeast Asia, Middle East) feature txuas ntxiv qhov chaw retarders, tiv thaiv ntxov ntxov nozzle clogging nyob rau hauv ambient kub tshaj 40 degree. Mixes destined rau sub-zero kev khiav hauj lwm muaj xws li ceev-ceev hardening accelerators.

Cov lus nug nquag nug (FAQ)
Dab tsi ua rau ntau qhov rov qab poob thaum lub sijhawm siv phom?
Peb lub ntsiab yog vim li cas dej siab tsis raug (dej siab yuav tsum siab tshaj conveying cua siab los ntawm 0.15 MPa), lub nozzle lub kaum sab xis tsis zoo (nozzles yuav tsum tsuag perpendicular ntawm 90 degree), thiab tus neeg teb xov tooj nyob deb (kev khiav hauj lwm tshaj 1.2 meters thiaj li aggregate compaction tshaj tawm).
Can gunning castable match lub cev lub zog ntawm cov uas tsis muaj cement castables?
Kev txhaj tshuaj ntub dej nrog ntom matrix additives ua tiav 90% mus rau 95% ntawm cov qauv castable compressive zog. Cov phom qhuav feem ntau ua tiav 75% mus rau 85% lub zog vim qhov ntim me ntsis porosity, uas yog qhov txaus txaus rau kev kho kub kub thiab hnav hauv ob sab phlu.
Ntev npaum li cas yuav tsum tau kho cov phom kub kub kho ua ntej rov pib lub qhov cub tawg tag?
Vim tias cov phom kub siv cov hluav taws kub uas nyob hauv phab ntsa thiab cov tshuaj tua kab mob ceev ceev, thaj chaw kho mob hauv 30 mus rau 60 feeb. Lub tshuab hluav taws xob tuaj yeem coj rov qab mus rau qhov ntsuas kub ua haujlwm tom qab maj mam nce siab (20℃txog 30℃ib teev) txhawm rau tsav cov av noo kom nyab xeeb.
