1. Market Background

In Kazakhstan, large steel castings for mining and heavy machinery are produced in high volumes and heavy unit weights. If they cannot be transferred quickly into a heat treatment furnace for quenching after pouring, problems such as uneven microstructure, cracks and distortion easily occur. Traditional fixed heat treatment furnaces rely on overhead cranes for loading, with long logistics routes and waiting time. As a result, production rhythm and yield are difficult to stabilize, and many foundries are turning to more flexible forklift type heat treatment furnace solutions.

2. Customer & Application Scenario

The customer is a foundry supplying large castings for mining and heavy equipment. Single castings can weigh several tons and are produced in stable batches. Their original fixed heat treatment furnace required frequent crane lifting, and the long sequence from pouring to loading often delayed fast quenching cycles. In some cases, castings missed the ideal quenching window because the heat treatment furnace was not available. The customer wanted to add multiple forklift type heat treatment furnaces to move castings directly from the pouring area into the furnace.

3. Our Solution (Product & Specifications)

Wuxi Wondery Industry Equipment supplied five forklift type heat treatment furnaces with the following key parameters:

• Working chamber: 3×2.4×1.5 m

• Maximum temperature: 1200°C

• Loading capacity: 7 tons per furnace

Each heat treatment furnace has a bottom structure that can be completely handled by forklift. Castings placed on special racks are driven directly into the furnace without multiple crane operations. With several forklift type heat treatment furnaces arranged in parallel, the customer can schedule different casting sizes and recipes flexibly. A multi-zone control system with programmable curves ensures uniform heating, soaking and equalizing of heavy sections inside each heat treatment furnace.

4. Customer Feedback

After commissioning, the customer reported that the time window from pouring to loading into the heat treatment furnace was significantly shortened, and fast quenching processes became easier to execute as planned. Overhead cranes were freed for mould and large-component handling instead of routine loading. The 3×2.4×1.5 m space and 7-ton capacity matched their main casting size range, avoiding both under-utilization of the furnace and “too small to fit” problems.
The customer also noted that the Wuxi Wondery Industry Equipment heat treatment furnaces offer stable lining performance, controllable energy consumption and simple maintenance, leaving room for future capacity expansion.

5. Conclusion

For Kazakhstan foundries focusing on heavy steel castings, a heat treatment island built with multiple forklift type heat treatment furnaces helps balance part weight, safety and production rhythm. The forklift type heat treatment furnace solution from Wuxi Wondery Industry Equipment is well-suited for plants planning new lines or upgrading from a single furnace to multi-furnace operation.
