Therefore, the protective coating should be applied to the surface of the roller before entering the kiln. The sizing length is generally better than the effective width of 100mm in the kiln, and the thickness is 0.8mm-1.2mm. The concrete use method is introduced in the clear reference roller protection coating.--Before loading into the kiln, the roller should be fully dry (about 1-2 days) at the side of the kiln or the top of the kiln before it can be used in the kiln.--Clean the surface of the roller and stick regularly and attachments on a regular basis. The roll rod is a brittle material, and it is necessary to avoid knocking, impact, punching and other methods that easily generating mechanical stress.--When the roll bar is replaced, it is generally better to cool down to 800ºC.And as fast as you can ,no matter draw out or put it into kiln. The extracted roll rod should adopt the correct cooling method to prevent the wind crystal caused by local splat cooling--When the rod is drawn at high temperature, the roller should be swiped quickly and rotated. It is best placed on a dedicated rotary support with a fire resistant cotton to keep rotating until the temperature drops below 600 degrees, or the insulation cotton is covered to slow down. The hot roll rod pumped out should not contact the ground directly, and avoid contact with the cold metal and the object with too large temperature difference with the roll bar.--After grinding of Replaced Sticky dirty roller, It is also necessary to carefully check its straightness, diameter and so on in order to be used again.[note] The use method above is the general use of roll rod, ZIBO CHAOXIN CERAMIC TECHNOLOGY CO.,LTD has the final rights to explain the whole article above.other productsCompany ShowZibo Chaoxin Ceramics Technology Co., Ltd. as a new and hi-tech ceramic manufacturer with excellent abilities of technology research, manufacture and distribution, is located in Zibo National New and High-tech Industrial Development Zone in Shandong Province, China.We mainly produce various kinds of fine ceramic products, which in material of zirconium oxide (ZrO2), alumina (Al2O3), zirconium silicate (ZrSiO4), mullite (A3S2) and composite oxide ceramics.
