Polish Heat Treater to Add LPC System
“Another vacuum furnace from SECO/WARWICK will technologically strengthen Polish commercial heat treater – HART-TECH. The Group already has over 10 SECO/WARWICK brand solutions, and the current contract related to the order of the Vector vacuum furnace will provide this Partner with the ability to implement their proprietary vacuum, which has not been previously offered commercially in Poland. The proprietary process will be implemented thanks to Acetylene (LPC), Ammonia (LPCN) and a very efficient gas hardening system (25 bar).
The Vector vacuum furnace on order is equipped with a working space of 900x900x1200 mm that will allow for the heat treatment of a very large range of steel types, with the ability to implement a wide range of processes from hardening through vacuum carburizing and carbonitriding. The furnace will efficiently heat treat large packages of research, test and production elements. The main purpose of the solution will be to work on the implementation of vacuum carbonitriding technology services that HART-TECH can now offer to a wide range of customers.
The characteristic features of this design includes a round heating chamber with very good temperature uniformity +/-5oC, convection heating – a system improving the heat transfer efficiency during heating at lower temperatures and a very efficient cooling system based on a fan controlled by an inverter ensuring maximum hardening pressure of up to 25 bar abs.
The Vector for the HART-TECH commercial heat treating plant has been expanded with a gas system equipped with two acetylene mass valves, a hydrogen mass valve and an ammonia mass valve. Thanks to the expanded gas cabinet, the furnace can use three gases for various technologies: acetylene, hydrogen and ammonia.
“This solution will help us to put into action a project concerning the implementation of vacuum carbonitriding technology at the HART-TECH plant with our customers in mind. We want to implement the low-pressure carbonitriding process and be able to use it in mass production. By expanding the machine park with a new vacuum furnace, we will also significantly shorten the waiting times for heat treatment for our current and future customers. The large workspace will significantly increase our capabilities for processing elements hardened in gas. Thus, we will be able to gradually switch from hardening elements in oil to hardening in gas, which is more efficient, cleaner and ensures smaller deformations.” – says Dr. Eng. Robert Pietrasik, President of HART-TECH.” Did you like this article? Click here to subscribe to The Monty.
