Pit Type Furnaces for Quenching

Product Introduction

Our Pit Type Furnaces for Quenching are specialized vertical heat treatment systems designed for the efficient and precise quenching of long, heavy, or vertically oriented components. These furnaces are installed in a pit below floor level, allowing for easy loading of tall parts by overhead cranes. The vertical design ensures uniform heating and rapid, controlled transfer to the quenching medium, which is crucial for achieving desired metallurgical properties in components like shafts, rods, and tubes. Ideal for industries requiring high-quality hardening and tempering of elongated parts, our pit type quenching furnaces provide exceptional temperature uniformity and controlled cooling, ensuring consistent hardness, strength, and microstructure across the entire length of the treated material.

Working Principle

Pit type furnaces for quenching operate by heating long or vertically oriented components in a controlled environment, followed by rapid and controlled cooling to achieve desired metallurgical properties. The process begins with loading the workpiece into a basket or fixture, which is then lowered into the pit furnace from above using an overhead crane. The furnace is sealed, and the components are heated to the desired austenitizing temperature. After the soaking period, the heated workpiece is rapidly lifted from the furnace and transferred to a quenching medium (e.g., oil, water, or polymer) to achieve the desired hardness and microstructure. The vertical design and rapid transfer minimize heat loss and ensure effective quenching, especially critical for long components where uniform cooling is essential. After quenching, the material can be further processed, such as tempering, to achieve final properties. This design allows for efficient handling of tall loads and precise control over the heat treatment cycle.
