Abstract

The invention provides a product heat treatment process for solving the problem of generation of cracks in products, nonuniform density and low heat treatment efficiency in the prior art. The productheat treatment process comprises the following steps: (S1) products are positioned in a first temperature environment for preheating; (S2) the products are positioned in a second temperature environment for roasting or insulation; and (S3) the products are positioned in a third temperature environment for cooling; the first temperature environment and/or the third temperature environment are constant temperatures; the second temperature environment is a constant temperature; and the temperature of the second temperature environment is higher than the temperatures of the first temperature environment and the third temperature environment. The products are transited in the heating and cooling process, so that the condition of extreme cooling and extreme heating is prevented, and the qualityof the products is improved.

Description

technical field [0001] The invention relates to heat treatment, in particular to a product heat treatment process. Background technique [0002] When heat-treating heat-resistant bricks and metals, there are often extremely cold and extremely hot heating characteristics, resulting in cracks in the product and quality problems. Realize continuous non-stop production, affecting production efficiency. [0003] At present, the known electric heat treatment kilns are intermittent, that is, the products that need to be heated are first pushed into the kiln by a drying car manually or semi-manually, and then heated, roasted, and cooled according to the heating curve, and then the finished product is dried manually. The car is rolled out and sent to the finished product warehouse. However, the output of this intermittent heat treatment kiln is small, the high-temperature kiln depends on natural cooling, the thermal system is frequently adjusted, the thermal efficiency is low, the ...
