Device for simulating and measuring heat flux of continuous casting covering slag

Abstract

The invention provides a device for simulating and measuring a heat flux of continuous casting covering slag, and the device comprises a heat flux emission system, a copper mould crystallizer, a power control system, a data acquisition/computer control system and a digital imaging system, wherein one end of the power control system is connected with the heat flux emission system and the other end of the power control system is connected with the data acquisition/computer control system; the copper mould crystallizer is placed below the heat flux emission system; and the digital imaging system is arranged beside the copper mould crystallizer. According to the invention, by virtue of comprehensively simulating a working condition and approaching to an actual production, the heat flux under instantaneous and stable conditions of the covering slag can be measured, and the size of the interface heat resistance between a slag film and a copper mould can be measured; and meanwhile, the thickness of the covering slag is accurate and controllable. Heat flux measuring equipment has the functions of controllable input heat flux waveform/amplitude and high testing flexibility; and the device has the advantages of good test repeatability, low equipment investment and maintenance cost, convenience for operation, stability, reliability, unique and novel structure, convenience for preparing test samples and low manufacturing cost, so that the device is novel heat flux measuring equipment.

Description

technical field [0001] The invention discloses a continuous casting mold slag heat flow simulation measuring device, which belongs to the technical field of testing the heat transfer performance of functional materials. Background technique [0002] According to the statistics of the World Iron and Steel Association in 2010, the world's total steel production has exceeded 1.4 billion tons, and my country's total steel production has reached 627 million tons, accounting for about 45% of the world's total production. Among them, more than 95% of iron and steel products are produced by continuous casting technology. Mold powder is a material widely used in the continuous casting process of iron and steel. It has the functions of heat insulation, preventing secondary oxidation of molten steel, and absorbing inclusions in molten steel. , lubrication and control of heat transfer. The utilization rate of mold slag in the continuous casting process reaches more than 80%. The series...
