Embodiment Construction

[0009] A double-push-plate high-temperature sintering kiln for producing vanadium-nitrogen alloys of the present invention includes a main kiln 1, an auxiliary kiln 2, a kiln head propulsion mechanism 3, a kiln tail propulsion mechanism 4, an electric heating system, an air intake system, and an exhaust system and control systems, etc.

[0010] Such as figure 1 As shown, the length of the main kiln 1 is set in the range of 10-50 meters according to the output, the effective section of the furnace is set in the range of 720mm-1000mm in width, and 340mm-500mm in height. Sub-reductive nitriding and K removal + / Na + section, high-temperature firing compact section, cooling section for nitrogen fixation, and cooling section.

[0011] The temperature of the primary reduction and drainage section is controlled below 900°C. According to the length of the kiln, it can be divided into 2-6 temperature zones. High-grade electrothermal alloy wires are used to heat and control the tempe...

Abstract

The invention provides a double-pushing-plate high-temperature sintering kiln for producing vanadium-nitrogen alloy. The kiln comprises a main kiln (1), an auxiliary kiln (2), a kiln head pushing mechanism (3), a kiln tail pushing mechanism (4), an electric heating system, an air inlet system, an air exhaust system and a control system, and the main kiln (1) is provided with a primary restoration and water draining segment, a secondary restoration nitridation and K+ / Na+ discharging segment, a high-temperature sintering densification segment, a cooling nitrogen fixing segment and a cooling segment in the longitudinal direction.

Description

technical field [0001] The invention relates to the technical field of kiln equipment, in particular to a high-temperature sintering kiln. Background technique [0002] As a new type of steel additive, vanadium-nitrogen alloy can replace ferro-vanadium for the production of micro-alloyed steel, and can greatly improve the comprehensive properties of steel such as strength, toughness, ductility, and thermal fatigue resistance. It can promote the upgrading of steel products at a low cost, improve the safety of buildings and their products in practical applications, reduce the amount of steel used, and save construction costs. It can be said that the application of vanadium nitrogen alloy in the steel industry is more and more common. [0003] In the prior art, the methods used for industrial production of vanadium-nitrogen alloys mainly include the following methods: one of them is conventional continuous high-temperature sintering kiln production, which adopts the furnace st...
