Composition of roller box:
Roller box main case, plate, (left and right)roll shaft, 8-shaped pannel, (left and right)eccentric locking collar parts, taper sleeve, adjustment feed screw and nut.
Technical characteristics:
1, Roller box adapt carbon steel to make sure the intensity of case. And use the annealing aging treatment to guarantee the stability of casting. It is not allowed to have holes, sand holes and cracks after roughing. Main case use high accuracy too to produce every holes to insure the total accuracy and the interchangeability & versatility between panel and main case. Rear side plate and front plate use No. 45 steel to temper. Main case, rear side plate and front plate used high accuracy machining tool( such as NC working centre) to ensure the high accuracy requirement of the location of eccentric locking collar and roll shaft.
2, Roll shaft used low carbon alloy steel blank, after roughing, axis need to take ultrasonic flaw detection process to quench. In order to ensure the tooth surface with high hardness, tooth surface need to take carburizing and quenching treatment after semi-finishing. Fine grind of every round and the back of axis insure its accuracy & durableness with taper sleeve and tooth surface. When the produce process of roll shaft finished, we need to take the balance test to insure the rotary accuracy during roll shaft's high speed rotation(7500 Rev / min).
3, Eccentric locking collar adapt carbon steel workpiece, inner diameter and eccentric round used fine machining tool to ensure the eccentric distance and accuracy of inner and outer diameter. Then, the adjustment accuracy of roll gap and the Interchangeability of every eccentric locking collar are ensured.
4, The front panel, real plate and internal parts are mostly made of medium carbon steel and processed by hard chrome plating and anti-corrosion treatment to increase the lifetime.
5, To make sure the assemble accuracy of roller box can reach the design requirement, a four-hour idling high-speed trial is conducted upon the assembly of roller box and bevel gear box, a smooth and stable sound and no oil leakage from the joint surface are necessary.

Process Flow:
Scrap to rebar:
Scrap → Smelting furnace → CCM(Casting) → ( online heating furnace) → roughing mill machines → intermediate rolling mill machines → finishing rolling mills → shear → cooling → sizing →collecting → packing → rebar storage;
Billet to rebar/wire rod:
Steel billets → reheating furnace → roughing mill machines → intermediate rolling mill machines → pre-finishing mills → shear → cooling → sizing →collecting → packing → rebar storage;
(Pre-finishing mills → shears → wire rod block mills → pinch roll and laying head → coil cooling conveyor → coil collection station → PF line → packing → wire rod storage )
Main Features:
1) Complete continuous rolling,control rolling,control cooling rolling process setting.
2) Adopting advanced world famous brand components in machine key parts ,electric parts and operation parts.
3) The rolling process is smooth,finished products have high precision and quality with high production yield.
4) Running in a high automatization and intellectualization,save manpower.
5) Comprehensive service for equipment supply, layout design, after-sales installation and commissioning services.
Product Detailed Images:
Roughing/intermediate angle steel hot rolling mill
Name:Housingless Mill "short stress path"
Brand:Hangji
Original: China
Feature:
-- Long roll lifetime.
-- The roll gap neutrality better and easy to operate.
-- Fast roll change, high automation efficiency etc.
-- Short stress line model much better for wire rod
and bar production.
Pre-finishing mill/Modular rolling mills with H-V arrangement
Name: Modular rolling mills with H-V arrangement
Brand: Hangji
Original:China
Feature:
-- The roller gap is adjusted by using the eccentric locking collar, by adjusting the lead screw and nut , the eccentric locking collar will spin and then drive the roller shaft to move symmetrically, in so to achieve the adjustment of roller shaft gap. The best advantage of this adjustment method is that the central line will be kept unchanged.
-- By using the thrust bearing that fixed at the end of the roller shaft, we can effectively prevent the axial shift of the roller shaft, in so to ensure size accuracy of the product.
-- The size and structure of the roller box for horizontal framework and vertical framework are the same, all the parts are interchangeable.
-- The power transmission and speed control are conducted by a pair of spiral bevel gears in the transmission box, the reducer is omitted from the transmission system of the vertical rolling mill, so that the whole equipment is lighter and smaller.
-- As the horizontal framework is completely symmetrical, it can be rotated 180°, so it can be shared by two production lines that located at its right and left side.
-- Guides device
The entrance of roller box has installed scroll guide and slip guide, the exit of roller box just has slip guide, slip guide is lubricated by special lubrication device.
