HOT STRIP MILL — HIGHEST PERFORMANCE FOR NEW AND EXISTING STEEL MILLS The demand for hot rolled strip is growing in multiple ways. To remain competitive, new and existing mills must meet this challenge in the best possible way. The production of hot strip is a key element of steel production.
Roller mills are also more sensitive to instantaneous changes in the feed rate than are other pieces of process equipment. Feeding a roller mill directly from a screw conveyor or bucket elevator will cause surges in the feed rate that the roller mill “sees” instantaneously unless some damping system such as a surge hopper is used.

It requires analytical skills and understanding of manufacturing process. Production planning and control is an essential part to run any business in the market because it can affect the quality of
Joseph Orlicky, author of the definitive Material Requirements Planning (MRP): The New Way of Life in Production and Inventory Management, said, "Never forecast what you can calculate."Nowhere is this rule more evident than in the manufacturing industry, where determining the right amount of raw material for current demand is a challenge.
Energy Efficiency in a Steel Rolling Mill by Effective Planning (Case Study) Page | 12 costs , in particular, the need for differentiated production, short lead times and precise delivery dates have further determined the industrial interest for the ministeel plant configuration.
Sep 10, 2018· It is because; the production time of an order is directly proportional to the vendor’s production capacity. So it is very important that marketing and planning personnel should aware of the production capacity of their production units. The capacity of a factory is primarily expressed in terms of total machines factory have.

• Production Bill of Materials (BOM) • Routings • Inventory Another way to describe the production process is to say that a person can use recipes to make things: the Production BOM is the list of ingredients, the routing tells the person what to do with the ingredients to obtain a finished product, and
Key Feature of Process Control: Detection of Periodic Defects Rolls and rollers are the most heavily used parts of a rolling mill. Due to wear from contacting hot material with great force, their lifetime is limited. Although rolls are refurbished in the roll shop regularly, they occasionally crack before the end of the usual production cycle.
