Product Overview

Mesh Belt Salt Bath Tank (Continuous Isothermal Quenching Tank Liner). Mesh belt salt bath tank is the core anti-corrosion chamber component for continuous mesh belt isothermal quenching production lines. The tank holds molten nitrate salt quenching medium inside. Heat-resistant alloy mesh belt transports workpieces steadily through high-temperature molten salt liquid to complete bainite austempering & martensite martempering processes. Double-layer water-cooled structure isolates high temperature to protect furnace steel frame. Our tank features excellent molten salt corrosion resistance & zero leakage performance, ideal for mass continuous heat treatment of fasteners, springs, bearings, cutting tools and small hardware parts.

Material Introduction

SUS310S / 0Cr25Ni20 (Standard Grade)：Max continuous working temp ≤650℃, outstanding resistance to molten nitrate corrosion & oxidation. Cost-effective for regular isothermal quenching production lines.

HK-40 / Inconel 601 Nickel Base Alloy (Heavy-Duty Grade)：Long-term working temp up to 700℃, superior intergranular corrosion resistance against molten salt. Resist perforation & leakage under 24/7 continuous heavy-load operation, perfect for high-output automotive fastener heat treatment lines.

SUS316L Stainless Steel (Low-Temp Washing Tank)：For low-temperature salt tank & cleaning tank below 400℃, good acid & alkali salt mist resistance, lower investment cost.

Main advantages

1. Double-Layer Hollow Water Cooling Interlayer Design：Circulating cooling water flows between inner & outer tank walls to control outer surface temperature under 60℃, prevent furnace frame thermal deformation and stabilize molten salt temperature for consistent quenching hardness.

2. Full Air-Tight Penetration Welding, Zero Leakage Guarantee：Integrated CNC bending forming with full argon arc welding on all seams. Every tank passes hydraulic pressure leak test before delivery, completely avoid molten nitrate leakage that damages equipment & pollutes production line.

3. Thickened Anti-Corrosion Plate With External Reinforcing Ribs：Heavy-gauge inner plates with outer support strips to offset thermal expansion stress from hot molten salt, anti-deformation & anti-cracking under long-term continuous operation.

4. Integrated Mesh Belt Channel Opening Design：Seamless inlet & outlet channel connects front & rear mesh belt furnace, effectively block salt mist backflow to protect front muffle tube from nitrate corrosion damage.

5. 100% Non-Standard Customization Support：Customizable tank length, width, depth, inlet/outlet flange & cooling pipe connectors per customer old tank or equipment drawings, compatible with all domestic & imported continuous mesh belt austempering furnaces.

Application Industries

1.Automotive fasteners: bolts, nuts, screws, suspension springs austempering

2.Bearing components: miniature bearings, needle rollers, shaft sleeves martempering

3.Hardware cutting tools: drill bits, taps, milling cutters, chains, spring clips bainite treatment

4.Precision mechanical small parts: pins, snap rings, stamped components low-deformation heat treatment

5.Matching equipment: continuous mesh belt isothermal quenching furnace, nitrate tempering furnace, mesh belt martempering production line

FAQ

Q1: How long is the service life of mesh belt salt bath tank?

A: SUS310S version: 10–16 months under normal production; HK40/Inconel alloy version can reach 2–3 years, service life depends on daily working temperature & production load.

Q2: Can you copy the dimension of my original old salt tank?

A: Yes, send us dimension drawings or photos of your used tank, our engineer provides free design & quotation within 24 hours.

Q3: Does the tank leak molten salt easily?

A: All welding seams are full penetration welded, each finished tank passes strict hydraulic leak test, no molten salt leakage during long-term mass production.

Q4: What package for ocean shipping?

A: Custom solid wooden case with foam & steel support inside, anti-collision & moisture-proof for long sea transportation.
