Desulphurization lance for iron pretreatment

LMM GROUP has unique design on the construction of the lance. The refractory is made by steel fibre reinforced ultra-low cement castable with corundum, high quality bauxite and mullite as main materials. With ten years of experience in continuous improvement, LMM GROUP desulphurization lance is characterized as stable quality , no-choking,

Dephosphorization lance for iron pretreatment

Although the metal structure of dephosphorization lance is similar to that of desulfurization lance, the use environment is quite different. Based on the successful experience of developing desulfurization lance, according the requirement of iron dephosphorization, LMMGROUP R&D personnel developed dephosphorization lance with the characters of stable quality, good service performance and long life, and rank in the leading position in China.

Fluid field simulation

Equipped with state-of-art water simulation and digital modeling lab for thermal devices used for steelmaking, LMM GROUP can provide steel mills with lab simulation on fluid, thermal filed and particle movement track, etc. of high temperature devices such as ladle, tundish and re-heating furnaces. Those simulation can provide scientific evidences to design better and long lasting refractory lining for ladle and tundish

Comprehensive refractory design

The selection of refractories and zone lining concept are the important parts in comprehensive refractory management for high temperature devices.

Based on water simulation and modeling tests and enriched experience of our technical staff, LMM GROUP can design and provide the mostly appropriate refractories and zone lining as per customers needs and working conditions of different zones in ladle lining so as to increase the service life of refractories .

Design and production of mould and installation tool

The design of moulds and necessary tools for refractory installation is also the important part for comprehensive refractory management

The project and design team at LMM GROUP is composed of talent professionals from mould design , mechanical processing and thermal engineering. Together with refractory engineers, they can develop unique equipment and tools for refractory installation and maintenance according to the needs on site. Those equipment and tools can ensure fluent and effective installation and also refractories, provided by LMM GROUP, to reach the maximum performance. The mould, designed especially for the installation of monolithic working lining and safety lining, is patented by LMM GROUP.
