Menene fa’idodin matsakaicin mitar tanderu ramming kayan da kayan simintin gyaran kafa?

Kayan ramming yana nufin abu mara siffa wanda aka gina ta hanyar ramming (da hannu ko na inji) kuma ya taurare a ƙarƙashin dumama sama da zafin jiki na al’ada. Ana yin ta ta hanyar haxa aggregates masu raɗaɗi, foda, masu ɗaure, abubuwan haɗawa, ruwa ko wasu ruwaye tare da ƙayyadaddun gradation. Dangane da rarrabuwa na albarkatun ƙasa, akwai manyan alumina, yumbu, magnesia, dolomite, zirconium da silicon carbide-carbon refractory ramming kayan.

Ana kwatanta kayan ramming masu jure wuta da sauran kayan amorphous. Kayan ramming sun bushe ko bushe-bushe da sako-sako. Yawancin su ba su da mannewa kafin su yi. Saboda haka, kawai ƙarfi ramming zai iya samun tsari mai yawa. Idan aka kwatanta da castables da robobi, kayan ramming suna da mafi girman kwanciyar hankali da juriyar lalata a yanayin zafi mai girma. Duk da haka, shi ma ya dogara da zaɓi na kayan inganci, kuma madaidaicin rabo na pellets da foda shima yana da alaƙa sosai.

Abubuwa masu ƙonawa da ƙwanƙwasawa duka kayan ƙyama ne, amma kuma akwai bambance -bambance tsakanin su biyun:

1. Bambance-bambancen da albarkatun kasa abun da ke ciki: The ramming abu ne yafi wani unshaped refractory abu sanya daga wani barbashi gradation tara da foda da wani ɗaure da Additives, wanda aka yafi gina ta manual ko inji ramming.

2. Ramming kayan sun hada da corundum ramming kayan, high-alumina ramming kayan, silicon carbide ramming kayan, carbon ramming kayan, silicon ramming kayan, magnesium ramming kayan, da dai sauransu Kamar wutar lantarki kasa ramming abu, silicon carbide, graphite, lantarki calcined anthracite. a matsayin albarkatun kasa, gauraye da ire-iren abubuwan da suka hada da foda mai kyau, gauraye da siminti ko guduro mai hade a matsayin mai ɗaure da kayan girma. Ana amfani da shi don cike ratar da ke tsakanin kayan sanyaya tanderu da masonry ko filler don matakin matakin masonry.

1. Castable wani nau’i ne na granular da kayan foda da aka yi da kayan da ba a iya jurewa da wani takamaiman adadin ɗaure. Tare da babban ruwa, ya dace da kayan da ba su da siffar da aka kafa ta hanyar simintin gyare-gyare. Manyan sassa uku na castable sune babban sashi, ƙarin bangaren da ƙazanta, waɗanda aka raba zuwa: tara, foda da ɗaure. Abubuwan da aka tara sun haɗa da silica, diabase, andesite da waxstone.
