Abstract

The invention discloses a system for measuring thermal insulation effects of metallurgy thermal insulation material and particularly relates to a system for measuring the thermal insulation effects of molten iron thermal insulation material. The system mainly comprises a testing furnace, automatic temperature collecting equipment and a computer data processing system. The testing furnace is a cylindrical furnace formed by alumina fiber lightweight refractory material and provided with a cylindrical hollow-structured hearth. The top and the bottom of the hearth are circular. The lateral wall of the hearth is vertical to the top and the bottom of the hearth. Thermal insulation cotton is disposed between the outer wall of the hearth and a furnace shell. Heating element silicon carbon bars are embedded in the lateral wall of the hearth to guarantee that the heart is evenly heated. A thermocouple is fixed at the bottom, close to the upper surface, of the hearth. The automatic temperature collecting equipment is respectively connected with the other ends of the silicon carbon bars and the thermocouple. Temperature signals are converted into voltage signals to be input into a DTW temperature control instrument through AD595, and a computer collects the temperature displayed by the precise temperature control instrument through LONWORKS and automatically draws the temperature curve changing along with time. The system has the advantages that the testing furnace is small-sized, simple, convenient and safe to operate, and especially suitable for lab researches; the whole system uses combined automatic control, and the thermal insulation effects of thermal insulation material is visually reflected.

Description

technical field [0001] The invention relates to a system for measuring the thermal insulation effect of metallurgical thermal insulation materials, in particular to a system for measuring the thermal insulation effect of molten iron thermal insulation materials. Background technique [0002] In the entire molten iron steelmaking production process, the heat loss and temperature drop are relatively large during the transportation of molten iron. If the temperature of molten iron transported to the steelmaking furnace does not meet the requirements of steelmaking production, the quality of steel will be affected. At present, different types of hot metal heat preservation agents are continuously produced. How to quickly and accurately measure the heat preservation effect of heat preservation agents is an important problem to be solved in the theory and practice of hot metal heat preservation. In view of this, according to the fact that the heat of molten iron in actual metallu...
