High-temperature continuous thermal treatment furnace for saw blades

Abstract

The invention discloses a high-temperature continuous thermal treatment furnace for saw blades, which comprises a shell, an insulating layer, a thermocouple and a heating module in the insulating layer, wherein the heating module comprises a heating chamber arranged along the advancing direction of a saw blade, a heating rod vertically passing through the insulating layer and extending into the heating chamber, a muffle pipe in the heating chamber, and a ceramic guide supported by a bracket in the muffle pipe; the heating chamber consists of a plurality of repeating units which are spliced inturn; each repeating unit is enclosed by a base, side walls symmetrically arranged on two sides, and a top cover vertically passing through the insulating layer; and each side wall comprises a lateral standing part and a flat eaves part arranged on the inner side of the top end of the lateral standing part, wherein the inner side face at the bottom end of the lateral standing part is in sealed fit with the base; the inner side face of the flat eaves part is a vertical plane and is in sealed fit with the side wall of the top cover; two ends of the inner side of the lateral standing part are provided with baffles used for supporting the top cover; and the flat eaves part between the two baffles is provided with a through hole for the heating rod to pass through. The thermal treatment furnace heats the saw blades in the muffle pipe through the heating rod, the temperature rise is quick and the efficiency is high.

Description

technical field [0001] The invention relates to a high-temperature heating furnace, in particular to a high-temperature continuous heat treatment furnace for saw blades. Background technique [0002] Metal saw blades must undergo heat treatment after processing to improve its performance. In order to improve production efficiency, saw blades are often subjected to continuous heat treatment before being cut into pieces. Such as figure 1 Shown is a cross-sectional view of an existing saw blade heat treatment furnace, which includes a casing 101 and insulating cotton 102 filled in the casing 101 , and a heating assembly arranged along the traveling direction of the saw blade is arranged in the center of the insulating cotton 102 . [0003] Such as figure 2 and image 3 As shown, the heating assembly includes a heating tube 103 and a muffle tube 105 that pass through each other. The heating tube 103 is on the outside and is made of white corundum ceramics. The outer wall is...
