Characteristics of semi-dry gunning machine Application scope and gunning effect

The semi-dry gunning machine is a rotor-type sprayer, which has the characteristics of small size, light weight, flexible movement, and convenient operation and maintenance. Maintenance and use of machine, coke square furnace wall, frame joint, carbonization chamber furnace roof brick, rising pipe, regenerator and other parts.

Semi-dry spraying material:

The semi-dry gunning material is used together with the semi-dry gunning machine, especially suitable for late-stage coke oven repair and maintenance.

1. According to the characteristics of coke oven repair, the provided semi-dry gunning material has the following performance:

① It has high adhesion under coke oven production conditions, and the adhesion rate can reach more than 85%;

② Facilitate stratification and flow, and ensure the repairing effect of deeper and larger areas;

③ The operation is simple, the gunning speed is fast, and the gunning capacity is 0.5-1.5 tons/hour;

④ It is easy to level and scrape to ensure the smooth surface of the repaired furnace wall;

⑤ The gunning material has good water absorption, and the gunning material after water absorption has good plasticity.

2. In order to meet the high temperature conditions of the coke oven, the provided semi-dry gunning material has the following thermal properties:

①It has certain flexural strength and compressive strength, and has good thermal shock resistance;

②It has the same thermal conductivity as refractory bricks and has lower porosity;

③In the case of high temperature, the strength increases rapidly, and the empty furnace time is short after repairing.
