Vertical induction heating continuous carbonization furnace

Abstract

The invention relates to a vertical induction heating continuous carbonization furnace which comprises loading boats and dredging boats that are overlaid vertically, as well as a hearth that consists of a cylinder heating unit and cylindrical sleeves concentrically arranged above and below the heating unit respectively. Materials are put into the loading boats and the dredge boats. A certain quantity of loading boats are positioned between every two dredging boats. The number of the loading boats arranged at intervals is proportional to a dredging time interval. Concave location grooves of inner chambers of the location sleeves are in clearance fit with convex dredging teeth on the outer sides of the dredging boats. When the dredging boats move relative to the upper and lower location sleeves, dust and barriers in a working channel are brought out of the working channel by the dredging boats, so that the effect of dredging the working channel is exerted, the technological requirement of dredging the working channel automatically at a fixed time is met, the blocking of the working channel caused by volatile matters in the furnace is eliminated, and the continuous working time and the service life of the carbonization furnace are prolonged.

Description

technical field [0001] The invention relates to a vertical induction heating continuous carbonization furnace, in particular to a vertical induction heating continuous carbonization furnace used for producing tungsten carbide and other powder materials in the cemented carbide industry. Background technique [0002] The existing Chinese patent number is 201010120322.1, and the name is "induction heating ultra-high temperature continuous carbonization furnace". In the actual carbonization production process, the equipment often needs to heat some mixtures containing low-temperature materials. For crystalline tungsten carbide materials, it is often necessary to add some low-melting point, low-volatile point crystal growth agents, such as potassium, sodium, lithium, etc., to the mixture of tungsten powder and carbon powder. These low-temperature materials volatilize into the working channel at a relatively high temperature. In the lower position, over a long period of time, lump...

These low-temperature materials volatilize into the working channel at a relatively high temperature. In the lower position, over time, lumps may be formed to block the working channel, resulting in the inability to continue production
