Pit Type Resistance Furnace | Precision Tempering Heat Treatment Solution
[City, Date] – Our company proudly introduces the Pit Type Resistance Furnace, a high-efficiency solution designed for the
tempering heat treatment of small and medium-sized metal and alloy parts. With a maximum working temperature of 650℃,
the furnace ensures uniform heating, reliable temperature control, and energy-saving performance—making it an ideal choice for
precision industries such as automotive, aerospace, machinery manufacturing, and metal processing.
What is a Pit Type Resistance Furnace?
A pit type resistance furnace is a vertical industrial furnace used primarily for tempering and low-temperature heat treatment.
Equipped with a powerful ventilator and stainless-steel air guide system, it guarantees uniform temperature distribution across
all parts, ensuring consistent quality in every heat treatment process.
Key Features & Advantages
-
Wide Application: Suitable for alloy steel, carbon steel, and non-ferrous metal parts.
