One stop service for steel industry

Vietnam-composite roll after-sales technical support

Our customer located in Ho Chi Minh City, Vietnam with continuous casting, rebar and wire production line.

LMM provided 4 sets of composite rolls used for rolling rebar 14mm&16mm in finishing mill K1 and pre-finishing mill K2. Customer sent us email on May 30th, indicating vertical cracks and block drops on rolls. LMM immediately had special meeting and dispatched 2 engineers to customer’s site and help them solve problem.

On 17th June, it is very hot in Ho Chi Minh, which does not stop the enthusiasm of our engineers, once arrived and visited site directly to understand the mill layout, feedback at site, problem investigation, data measurement and analysis and judgment, etc.

The on-site inspection does have some discrepancies with the data provided by the customer. After all, the customer is not professional enough on product. The observation of rolls is not comprehensive. Roll has transverse cracks and falling blocks, the surface has different traces like knife edge, which is caused by the impact of the end face of the rebar

In order to improve the site and production process for customer, we have investigated and tested the cooling water, water pipes and related parts.

At noon, Vietnamese friends used authentic Vietnamese cuisine to express their love for us. At the same time, they also show us the richness of Vietnamese seafood and the colorful diversity of local customs.

In the afternoon, we convened the steel factory technicians and opened a technical seminar to explain reason for the problems, as well as future solutions. During the free questioning period, the customer engineers asked a number of questions and got the satisfactory answers.

This technical visiting was very successful! The customer’s problem was solved and their production process was improved, which indirectly improved production efficiency and contributed to the creation of a happy life for the Vietnamese people.
