西日本設計工業 List of Products and Services

The temperature measurement and sampling of molten iron and molten steel are progressing towards automation due to the harsh working environment. Our company has commercialized this equipment based on the extensive experience and technology of our long-standing steel plant design team, and we are a manufacturer with a significant track record of deliveries. By designing equipment that matches the needs of users and the installation space, we are confident that we can provide facilities that will surely satisfy you. Additionally, the probe attachment and detachment device is generally installed on the operating floor, and it automatically attaches the necessary probes for measurement purposes to the holder of the lance body used for temperature measurement and sampling, from filling the probe to cutting it out, and it also removes the probe after measurement. Bomb-type samples can be automatically extracted and delivered to the gas transport pipe.

- Due to its special diaphragm structure, it can remove dust adhered to the seat surface and is widely used for valves for by-product gases such as blast furnace gas (BFG), coke oven gas (COG), and converter gas (LDG) generated from equipment in steel mills that contain a large amount of dust. - It allows for non-leak, complete shut-off and can also be used as a water seal valve to ensure further safety. - Developed and launched in 2014, there have been no significant trouble reports after delivery to domestic steel mills. - When used as a water seal valve, it does not require a large installation space like a V-shaped water seal pipe, and the amount of water needed for sealing is minimal, making it environmentally friendly and allowing for simplification of foundations, etc.

- Due to its special valve body structure, it can remove dust adhered to the seat surface and is widely used for valves for by-product gases such as blast furnace gas (BFG), coke oven gas (COG), and converter gas (LDG) generated from equipment in steelworks that contain a large amount of dust. - The double block structure allows for non-leak, complete isolation, and it can also be used as a water seal valve to ensure further safety. - The valve body (valve box) is spherical in shape, which provides a large gas passage area, smooth flow, and minimal pressure loss. - It has a proven track record of delivery to steelworks across the country, with few failures, and there are active valves that have been in service for over 50 years while undergoing overhauls. - When used as a water seal valve, it does not require a large installation space like a V-shaped water seal pipe, and the amount of water needed for the seal is minimal, making it environmentally friendly and allowing for simplification of foundations, etc. - By using NK valves in the currently promoted double block system, it becomes easy to install closing flanges in the downstream section.
