Coke Oven Door Glaze Prefabricated Parts and Riser Lining

Application

Mainly used for the door of coke oven

2 Process flow

Batching → Mixing → Decompression molding → Medium temperature baking → Mechanical glaze spraying → High temperature glazing firing → Inspection → Packaging.

3 Features

Simple structure, better sealing performance

The surface composite ceramic material coke oven door is composed of 6-7 large prefabricated parts, no longer requiring cast iron brick grooves, and has a simple structure. The new furnace door is composed of 6-7 large furnace door prefabricated parts with high-performance microcrystalline ceramic refractory glaze layers attached to the surface, with only 5-6 masonry joints, and better integrity and sealing.

 

Convenient construction

The surface composite ceramic material furnace door prefabricated parts have pre-buried fastening bolts before leaving the factory. When installing on site, you only need to fix the bolts to the furnace door frame. No masonry is required, and the installation is simple, which can shorten the construction time and reduce labor costs. The high-temperature glaze covered on the surface of the surface composite ceramic material furnace door prefabricated parts does not accumulate carbon or coke, and the later maintenance is also very convenient, and the labor intensity of later maintenance can be greatly reduced.

The surface composite ceramic material furnace door prefabricated parts adopt negative pressure high-frequency vibration molding during production, which reduces the porosity, improves the density and uniformity of the blank, and is attached with a high-performance microcrystalline ceramic refractory glaze layer on the surface, which has high strength, good wear resistance, and excellent erosion resistance, solving the problems of carbon and tar deposition and chemical penetration. High-performance microcrystalline ceramic refractory glaze has high refractoriness, strong adhesion, good ductility, and excellent thermal shock resistance. It will not peel off due to rapid temperature changes during daily use, and the use temperature can be from 500℃ to 1500℃.

Traditional furnace door materials need to be continuously maintained after half a year of use. The surface composite ceramic furnace door prefabricated parts have stable physical and chemical properties and greatly extended life.

(1) The surface composite ceramic material furnace door prefabricated parts have good thermal insulation effect, less heat loss, can improve the dry smelting efficiency (coking rate), and significantly reduce fuel consumption. The surface temperature is 20-30℃ lower than that of traditional furnace doors, which has a good thermal insulation and energy saving effect.

(2) It can increase the space of the coke oven carbonization chamber, improve the utilization rate of the coke oven space, and achieve significant results in reducing costs and increasing efficiency.

(3) The new furnace door has excellent sealing performance, no smoke and dust, no coke seepage, and the high-performance microcrystalline ceramic glaze covered on the surface does not accumulate carbon or coke, which can greatly improve the working environment of workers and reduce pollution to the environment.
