Glass furnace has transited to gas furnace which makes liquefied petroleum gas as fuel from the original traditional firewood kiln, after coal and heavy oil. Recently years, duo to the rapid development of private enterprises and poor production environment and conditions, which leads to fire and explosion accident of gas furnace, however, after the appearance of corundum block which is with thermal resistance, high thermal conductivity and good wear resistance, furnace becomes more safe and reliable.
As the raw materials of corundum block play an important role, and the raw material of corundum block contains bauxite, kaoline, clay and diatomaceous earth which have high fire resistance. The internal temperature of furnace generally can reach 350℃, and high temperature furnace can reach 2000℃ or so. Furnace is general heated through electric, coal, oil, gas or electromagnetic induction, at the period of low temperature, heat exchange is mainly based on convection heat transfer, however, at the period of high temperature, the radiation heat transfer is the main, with the increase of temperature, the role of radiation heat transfer is more and more, so the structure and the heat insulation of furnace are required to do well. Along with the progress of the world's industry, kiln structure is gradually optimized and energy saving rate is improve, which have a more stringent requirements for corundum block.
Zhengzhou Sunrise Refractory Co., Ltd can provide glass refractory which has passed the ISO international certified. Over 30 years producing and marketing experience, with reliable quality, competitive price and prompt delivery, Sunrise has established long-term business and cooperation relationship with many customers in different countries and regions. For any further information, Contact us, we will do our best to help you.
