Problems solved by technology

The heating method of a general tube furnace is induction heating by resistance wire, that is, heating the air within 10 mm outside the quartz tube, so that the heat is heated to the cavity through the wall of the quartz tube, and the material is heated up. Although this method is effective, the temperature rise Still slow, unable to meet the heating requirements of special materials

Abstract

The invention discloses a rapid heating furnace adopting an internal heating method. The rapid heating furnace comprises an electrode, an air inlet, a flange, a pressure gauge, pipe plugs, a heat preservation cavity, a base material and a quartz disc. The heat preservation cavity is formed in an equipment frame. A test tube is arranged in the heat preservation cavity. A heating element is fixedlyinstalled at the bottom end of the inside of the test tube and connected with the electrode. The quartz disc is fixedly installed above the heating element. The base material is placed on the quartz disc. The two pipe plugs are further symmetrically installed in the test tube. According to the rapid heating furnace, the electrode is connected with the heating element, an internal heating manner isachieved, a through pipe of an original tubular furnace is changed into the single-end test tube, the single-end test tube is arranged in the heat preservation cavity, heat of a temperature field canbe protected against loss while rapid heating is achieved, and therefore, the effect of continuously keeping the high temperature in the cavity after heating is stopped is achieved.

Description

technical field [0001] The invention relates to the technical field of fast heating furnaces, in particular to a fast heating furnace with internal heating method. Background technique [0002] Tube furnaces are very commonly used and important equipment in laboratories that require medium and high temperature conditions at this stage. The heating method of a general tube furnace is induction heating by resistance wire, that is, heating the air within 10mm outside the quartz tube, so that the heat is heated to the cavity through the wall of the quartz tube, and the material is heated. Although this method is effective, the temperature rise Still slow, unable to meet the heating requirements of special materials. [0003] Generally, when the heating tube furnace equipment grows materials, the materials in the chamber are heated by heat conduction. The growth materials thus obtained are not pure enough, the purity is not high enough, more by-products are produced, and the hea...
