Stainless Steel Annealing Furnace Wire Production Line

Stainless Steel Annealing Furnace Wire Production Line

The Stainless Steel Annealing Furnace Wire Production Line includes a wire drawing machine, an annealing furnace, a cooling pool, and an inverted take-up machine.

The main purpose of thorough annealing in the annealing furnace is to soften the steel and improve its machinability of the steel.

Stainless Steel Annealed Wire Production Line Production Equipment

1. Linear wire drawing machine consists of duckbill type pay-off frame or I-shaped wheel pay-off frame, LZ8/560 straight wire drawing machine, SC740 winding machine, man-machine interface screen, electrical control cabinet unit

4. Inverted take-up machine

0.75 kW cycloidal pin gear reducer, two types of winding diameters (600+400), 20 winding drums

Fuji brand inverter power 0.75KW

Winding speed: 60m/min, the winding can be controlled independently, and the machine can be started and stopped at the same time.

20 600 wire take-up machines (1480×460)

The height of the wire take-up machine is 2300mm, the total width is 900mm, and the total length is 10840mm. The height of the stepping device is 270mm and the width is 1050mm.

The heat treatment procedure of the annealing furnace is to heat the steel to 20~30°C higher than A3 point or 30~50°C higher than A1 point for a period of time, so that after the complete Worstine arrangement (or wollastonite and scheelite carbon arrangement) is formed body), at 50°C below point A1, the abnormal wavy body occurs sufficiently to obtain a softened material.

In addition, stress relief annealing is heating at 450~650°C below the abnormal point, and then slowly cooling to room temperature, which can eliminate residual stress during cutting, stamping, casting, and welding.
