Kiln body arched beam in high-temperature area of pushed slab kiln with nitrogen protection

Abstract

The invention relates to a kiln body arched beam in a high-temperature area of a pushed slab kiln with nitrogen protection. The kiln body arched beam is characterized in that middle arched beam bricks, inner arched beam bricks and outer arched beam bricks are included; a semicircular groove is formed on one junction surface of each middle arched beam brick, and the other junction surface of each middle arched beam brick is an junction surface; the two junction surfaces of each inner arched beam brick are inclined surfaces; one junction surface of each outer arched beam brick is an inclined surface; the oblique angles alpha of the inclined surfaces of the middle arched beam bricks, the inner arched beam bricks and the outer arched beam bricks range from 3 degrees to 10 degrees; mutually corresponding intermeshing steps are arranged on the inclined surfaces of the middle arched beam bricks, the inner arched beam bricks and the outer arched beam bricks respectively; the middle arched beam bricks, the inner arched beam bricks and the outer arched beam bricks are installed in bilateral symmetry; the semicircular grooves of the two middle arched beam bricks constitute an insertion hole; and a pin column is arranged in the insertion hole. The kiln body arched beam has the advantages of low possibility of loosening, less maintenance and repair, convenience in maintenance and repair and improved production efficiency.

Description

technical field [0001] The invention relates to a kiln body arch beam of a push plate kiln, in particular to a nitrogen atmosphere protection kiln body arch beam in a high temperature zone of a push plate kiln. Background technique [0002] At present, the nitrogen atmosphere protection pusher kiln is the sintering equipment in the production process of magnetic materials. The arch beam of the kiln body in the high temperature zone of the nitrogen atmosphere protection pusher kiln is made of many pieces of arch beam bricks. Once a small piece of arch beam brick falls off during the practical process of the kiln, it will easily cause the entire arch beam to collapse, thereby affecting production. On-site masonry is carried out at the customer's site where the nitrogen atmosphere protects the pusher kiln, thus reducing the production efficiency of the nitrogen atmosphere protection pusher kiln. Contents of the invention [0003] In view of the above disadvantages, the objec...
