Flat Bars

Instinox is a famous manufacturer of standard sizes and grades such as mild steel hot rolled steel flats which are available to customers in a range of standards size such as mild steel, mild steel , carbon steel etc. Instinox is a distributor of its products in more than 13 countries. All products have brand marking for identification. Instinox also manufactures customized products as per customers’ requirements. We ensure 100% best quality and tested products. We provide competitive pricing at affordable rates, cutting down our profits at minimum. Bars manufactured at Instinox have high pressure sustainability. Instinox provides its customers the facility of premium packaging and packing for 0 sea and air transport for the safety of products. WE successfully register 0% sales returns rates in the last two decades. We provide product replacement warranty at all times.

Instinox overcomes the problems of non-availability of goods since it has one of the largest warehouses in the industry. We supply the best grades as our products are made out of materials consistent with ASTM standards.

Flat bars are a kind of steel product bearing a rectangle section with a width range from 12 to 300mm and that of the thickness from 4 to 60mm. These are rectangular, flat section with squared edges in varying sizes. Flat bars are cost –effective and are suitable for a wide range of applications and distributed to construction, engineering, manufacturing, mining, grating, fabrication, and many other industries. These bars are versatile in nature and that makes it usable for various industries, along with excellent ductility and strength combination of steel. The specifications of flat bars can be described by the unit of thickness width. Flat bar can be used as hot-rolled finished product or billet cut from plates. These bars are available in more than 10 different sizes different in terms of their thickness. Flat bars can be purchased individually or as a bundle and we also cut to length for customized demands.

The flat bars rolling manufacturing process with a 70 mm diameter in an analyzed continual shape rolling mill is done in the first eight rolling stands. Feedstock before the rolling manufacturing process is controlled (bar dimensions, number of melting, finished surface) and then heated in a running beam furnace in accordance with the technology of heating of the steel grade. When heated to the required temperature, the roll is subjected to descaling operations that are generated by the heating process. The next stage is technological operations of rolling the bars in individual stands. After the hot rolling manufacturing process band is stored in the cooling table, where the bars cools down to ambient temperature. The last stage of production is cut band on trade lengths, quality control, weighing, packing and tagging (a type of bar, size, weight, grade of steel, etc.)
Improvised Round Bars Roll Manufacturing Process

In order to lessen the effect of non-uniform temperature distribution in the heat change to homogenize the round bar dimensions along with their length, should be carried out by regeneration heating furnace or change existing technology of roll manufacturing . Furnace repair is a long term suspension of production and the high cost of wear and tear repairs and the cost of the stopped mill.

Modifying an existing line roll manufacturing and rolling technology can be much lower financial outlay to minimize the existing problem. The pre- existing mill line should be equipped with temperature and rolled band speed sensors and measurement card – control, which should be connected on-line through the computers with the drives stand over the roll manufacturing. The suggested solution should be a rolling sequence equipped with sensors whose work is to measure the temperature and speed of the rolled band in real time. The signal from the sensor is transmitted by the measurement and control card to the computer with a program that, based on the data obtained will be controlling the speed of rolls mill stands.
