Burner brick for industrial kiln

Abstract

The invention discloses a burner block used for an industrial furnace. The burner block comprises a mental base, a fire-resistant internal bladder and a protective sleeve; the mental base is connected with the fire-resistant internal bladder, and a burner gun inlet opening of a burner gun and a spark plug spigotjoint for containing a spark plug are positioned on the mental base; the protective sleeve is covered on the outer side of the fire-resistant internal bladder, and the mental base comprises the following components of parts by weights: chrome occupies 15 to 30 portions, molybdenum occupies 15 to 30 portions, nickel occupies 15 to 30 portions, tungsten occupies 3 to 7 portions, and manganese occupies 30 to 45 portions; the fire-resistant internal bladder is composed of the followingcomponents of parts by weights: mullite occupies 25 to 35 portions, silicon occupies 3 to 8 portions, alumina occupies 20 to 40 portions, alundum powder occupies 20 to 30 portions, and a high temperature resistance cement occupies 5 to 10 portions; the protective sleeve adopts the material of mullite; a refractory fiber paper is arranged between the fire resistant internal bladder and the protective sleeve. The burner block used for the industrial furnace has the advantages of high temperature resistance, wear resistance and durable service.

Description

technical field [0001] The invention relates to a burner brick for an industrial kiln. Background technique [0002] Industrial kilns are widely used in ceramics, magnetic materials, electronic materials, metallurgy and other industries. The structure of general industrial kilns mainly includes: shell, furnace body, furnace, and refractory bricks are arranged around the furnace. It can prevent the heat in the furnace from dissipating to the outside of the furnace, reducing the heat consumption in the furnace. However, refractory bricks can only isolate convection and conduction heat transfer, but cannot effectively isolate radiation heat transfer, such as infrared radiation, so the heat in the furnace is still radiated to the outside of the furnace body through refractory bricks, resulting in Furnace cooling. The temperature of the kiln can generally reach over 1000°C during the working process, so the performance requirements for the burner brick are very high, and the re...

AI Technical Summary

Problems solved by technology

The metal base of German Horkod burner brick mainly contains iron and silicon, which has the defects of not being resistant to high temperature, easy to oxidize, and easy to expand and deform, and its metal protective sleeve is made of stainless steel, so it can only be used at around 1100 °C The working requirements of the kiln are not applicable to the higher operating temperature, which limits the working range of the kiln.

As a kind of consumable, burner bricks are all imported, and the cost is very high, which has caused a great economic burden to domestic enterprises.
