Abstract

The invention relates to the field of industrial bricks, and discloses a checker brick with plum blossom holes for an air heating furnace. The checker brick is provided with through holes which are equidistantly arranged and shaped like plum blossoms; each plum blossom-shaped through hole is formed by head-to-tail connection of six 120-degree circular arcs of the same size; the periphery of the checker brick is provided with a 120-degree circular arc hole and a semi plum blossom-shaped hole which is formed by sequentially connecting three 120-degree circular arcs; the upper end face of the checker brick is provided with grooves; and the lower end face of the checker brick is correspondingly provided with projections. The checker brick with plum blossom holes for the air heating furnace has large heating surface, good stability, large hot air flow, and good up and down air flowing effect, is not easy to block, solves the long-time problems of intensity smelting and low blast temperature, and improves the furnace temperature of a blast furnace.

Description

technical field [0001] The invention relates to the field of industrial bricks, in particular to a checker brick for a hot blast stove. Background technique [0002] Checker bricks are commonly used heat storage devices in heating equipment such as hot blast stoves and preheating furnaces, which can greatly reduce the amount of fuel used in industry. The checker bricks used in the prior art usually have round holes, small hole diameter, small heat storage area, small heat release, small hot air flow rate, and relatively high cost. Contents of the invention [0003] In order to solve the problems existing in the prior art, the present invention provides a plum-blossom checker brick for hot-blast stoves that can increase the flow rate of air and hot air, and has a good effect of passing up and down airflow. [0004] The present invention is achieved like this: [0005] A checker brick with plum blossom holes for a hot blast stove. The checker brick is provided with through...
