Heating furnace

Abstract

The invention discloses a heating furnace. The heating furnace is applicable to the Hopkinson pressure bar experiment and is used for heating a specimen on a pressure bar. The heating furnace comprises a furnace body, a heating element and a temperature control system; the heating element, which is fixed in the furnace body, comprises a silicon-molybdenum element and / or a carbon-molybdenum element, wherein the pressure bar can be inserted in the furnace body and the specimen is heated by the heating element; the temperature control system is electrically connected with the heating element. By arranging the silicon-molybdenum element and / or the carbon-molybdenum element as the heating element in the heating furnace, the highest heating temperature of the heating furnace can be increased to about 1200 DEG C and the speed of temperature rise is remarkably increased at the same time, moreover, because of the arrangement of the temperature control system, the heating power of the heating element can be conveniently controlled on the basis of the measured temperature of a thermocouple fixed on the specimen, consequently, optimal heating efficiency can be quickly reached, the heating precision can be increased, and meanwhile, the heating time can be shortened.

Description

technical field [0001] The invention relates to a heating furnace, in particular to a heating furnace suitable for Hopkinson compression bar experiments. Background technique [0002] In the Hopkinson pressure bar experiment, it is often necessary to use a heating furnace to heat the sample. The core heating component in the heating furnace is a heating wire, but the temperature that the traditional heating wire can heat is low and the temperature rise rate is slow. Generally, the heating wire can only be heated up to 800°C, and when it reaches or exceeds 800°C, the heating wire is very easy to fuse, resulting in the failure of the heating furnace to work normally. [0003] Moreover, the heating furnace using electric heating wire has poor heating efficiency and slow heating rate, and the electrodes are often damaged due to excessive temperature, which increases the cost of use and is poor in practicability. Contents of the invention [0004] The present invention aims t...

The core heating component in the heating furnace is the heating wire, but the temperature that the traditional heating wire can heat is low and the temperature rise rate is slow

Generally, the heating wire can only be heated up to 800°C. When it reaches or exceeds 800°C, the heating wire is very easy to fuse, which will cause the heating furnace to fail to work normally.

[0003] Moreover, the heating furnace using electric heating wire has poor heating efficiency and slow heating rate, and the electrodes are often damaged due to excessive temperature, which increases the cost of use and is poor in practicability
