Checker brick for hot blast stove

Abstract

The invention relates to a checker brick for a hot blast stove. Checker brick holes are formed in the end surface of a checker brick body, a locating groove and a locating pin are arranged on the peripheral surface of the checker brick body, and the depth of the locating groove is less than the length of the locating pin; and cold air can be distributed secondarily according to the pressure after the cold air enters the hot blast stove, and can pass through the checker brick evenly, therefore, a uniform heating effect can be achieved, and the heat of the checker brick can be effectively utilized.

Description

technical field [0001] The invention relates to a checker brick for a hot blast stove, which can realize uniform heating of cold air by the checker brick of the hot blast stove. Background technique [0002] Checker bricks are the intermediate medium for hot blast stoves to absorb and output heat. Existing types of checker bricks either cannot balance the air volume of the hot blast stove, or the balanced air volume is not good. When the hot blast stove heats the cold air, the cold air flows into the hot blast stove from the inlet at a speed of 35-45 m / s, and most of the air volume flows through a part of the masonry opposite the air inlet, because each of the original checker bricks is in close contact , which causes the cold air to not flow freely from one grid space to other grid spaces. Cause a large amount of lattice bricks not to be utilized, caused a large amount of waste. At present, there are also improvements to the checker bricks, and pressure and flow equalizat...
