Hot rolling mill steel bar production line manufacturer rebar making machine

Hot rolling mill steel bar production line manufacturer rebar making machine

Our company supply all kinds of steel wire /rebar/ flat bar/angel steel/H steel / steel bar production line productivity

 two types Steel production line:
1. Raw material is scrap steel iron
waste steel ----melting---- casting----mold unloading----sorting-----deliver to heating furnace----heating to 1150 degree to 1200 degree----- come out furnace----- rolling----- finished product ----packing---- sales
2. Raw material is steel billet

Steel billet ------Feed into furnace----- electric induction heating furnace ------feeding out of furnace---run in rolling table-----roughing rolling mill--run out lifting rolling table ------continuous rolling mills----Cooling bed input rolling table--chain type cooling bed----cut into Fixed-length -packing table

Covering area: 20m*100m,   Transformer capacity:3000KVA

5T/hour productivity, we suggest customer use 60*60 steel billets,this mainly decide cost of rolling mill.

PART 1: heating furnace 

Heating energy can use natural gas or heavy oil as medium, or electric heating.

1). Gas heating save cost , but it is suitable for continuous 24 hours working

2). If every day Intermittent work, for example, work 5hours, 8-10 hours, recommend you electric heating furnace, is more suitable .

For example, use electric induction heating furnace 2300KW, heating capacity : 5.2ton per hour.  The steel billet is fed into heating furnace, through feeding mechanism ,by automatic hydraulic type push steel billet , to be heated.

Technical parametes of steel billet electric heating furnace for steel bar production line  

The heating quality of the blank directly affects the energy consumption of the heating furnace, the life of the rolling mill, and the output and quality of the finished product.

The heating process of the blank mainly includes:

Billet heating temperature ,Billet heating time, 

Billet heating speed ,Billet heating uniformity,

Based on theoretical calculations and actual production experience, the billets should be continuously heated to 1050 to 1150°C in the furnace.

PART 2 : Rolling mills  

2.1.Rough rolling mills

The steel billet heated by the heating furnace is pushed out by the auto hydraulic type push steel billet machine one by one, and is fed into the Φ350 three-high mill through feeding out of heating furnace roller path and the run in rolling table.

2.2.use 3 groups Φ250×2 two-high mills ,one drag two (one group has two racks) continuous rolling mills.

PART 3.Cooling bed 

Cold Beds and Finished Products

The rolled part with the finished section enters into the cooling bed input track.

The rolling stock continues to lead to a 3000KN cold shearing machine, which is cut to a length of 6 to 12 meters by means of a sizing machine. After the sheared steel is inspected on the inspection bench, the fixed-length and non-sizing steels are placed in the finished product collection basket.
