Thermocouple combined brick with deformation damage preventing function

Abstract

The invention relates to a thermocouple combined brick with a deformation damage preventing function, and belongs to the field of thermocouple combined bricks. The thermocouple combined brick with thedeformation damage preventing function is formed by splicing two thermocouple brick bodies, wherein the two thermocouple brick bodies are arranged in an up-and-down mode and are spliced with each other. According to the thermocouple combined brick with the deformation damage preventing function, the combined brick with an elliptical groove hole replaces an original reserved square hole, and the elliptical hole is prefabricated in the middle when a square brick is manufactured through firing to be used for mounting of the thermocouple.

Description

technical field [0001] The invention relates to a combination brick for preventing deformation and damage to thermocouples, which belongs to the field of thermocouple combination bricks. Background technique [0002] Hot blast stove, the air supply system of blast furnace, generally consists of 4 hot blast stoves, 2 for delivery and 2 for firing. The detection of thermocouple temperature is very important to the hot blast stove during use. There are as many as a dozen thermocouples in one hot blast stove, and the temperature change at each position can reflect the use of the two stages of the hot blast stove, the furnace and the air supply. The problem can be fed back in time through the abnormal change of temperature. Moreover, the temperature point is connected to the PLC system to play an interlocking role. For the process production, the thermocouple is its eyes. The traditional installation method is prefabricated masonry square holes, using square bricks, the brick...

Problems solved by technology

The traditional installation method is prefabricated masonry square holes, using square bricks, the bricks are small in size (20*10cm), bricks and bricks are built with materials, and a square hole is reserved in the middle for installing thermocouples. This combination brick There are many disadvantages in the masonry method. With the increase of the age of the hot blast stove, the bricks inside are prone to deformation under the high temperature (12000) and high pressure (400kp) airflow. Because they are square bricks with four sides and corners, the stress area is large. , The interaction between bricks and bricks has a wide range, and long-term accumulation will cause the entire brick to fall off, which will directly damage the thermocouple
