Q:Measures to prevent cold rolling of packaged cold rolled steel coils? Who can give some professional opinions oh?
Cold rolled steel coils are generally sprayed antirust oil, according to user requirements, light, medium, heavy oil 3 types. Nevertheless, if the oil is volatile or in a humid environment, the steel plate comes into contact with the water for a period of time, indicating that it is beginning to rust.
Q:What are the characteristics of hot-rolled steel coils and cold rolled steel coils? What loading and unloading tools should be used? What items should be paid attention to?
Steel is usually stable in performance. One thing is that the environment should be dry, not rain, because the damp environment is easy to rust. As long as it's in a dry room, it's basically no problem.
Q:In the warehouse management system of steel coil
Warehouse is an important component of enterprise material supply system. It is also the tache of enterprise material circulation and storage, and it also undertakes many functions of material management. Its main tasks are to keep the stock well, to be accurate, to be of good quality, to ensure safety, to prompt the people, to produce, to be considerate, to reduce costs, and to speed up capital turnover.
Q:What is the material of steel coil 08F and what brand can be used instead?
Characteristics and applicable range of 08F:Its strength is low, and the steel is soft, plastic and tough. General use does not require heat treatment, but in order to eliminate the internal force due to cold processing, improve the cutting performance of steel, heat treatment can be carried out, cold processing can increase the intensity. Often used in the manufacture of stamping parts and carburizing parts, such as stamping products, sockets, enamel products, automobile shell, etc..
Q:On how to reinforce steel coils in a container
The inside of the container is rectangular, four angles with hook, so can the packing time for warehouse experienced workers in the upstairs said, with the steel wire rope and steel reinforcement will lock up, if the mud coil is hollow, the wire rope through the middle and then cross to get on fixed on the four corners, and on the floor on the wooden wedge nail to prevent steel coil rolling.
Q:Why is the steel tape tape head not fixed?
In this way, no matter how you measure, always be measured, from the ruler of the "0" bit began.The fixed ruler does not take this action when it is taken, which directly results in the thickness of the steel sheet that needs to be added or lowered to your readings;Activity design is designed to reduce error, and this is an advanced approach;
Q:Cold rolled steel coil steel, what is the difference?
Hot rolling is made of slabs (mainly continuous billets) as raw materials. After heating, strips are made from roughing mills and finishing mills.
Q:Why can hot rolled coils be placed outside?
Because hot-rolled steel coils are generally used as raw material for semi-finished products, they have to be further used for pickling and cold rolling to make more use. The rust and dust can be removed after pickling
Q:What does "steel roll number" mean?
According to the project schedule, track and coil encoding management to the quality of the products, which makes the production with a rational and quality after processing, troubleshoot save time, contribute to the automation of production smoothly, improve and stabilize the quality of products for production order arrangement and classification of coils.
Q:The strip tower height
Elimination measures: strictly control the shape of plate and reduce the serpentine; according to the different specifications of the strip, set up the take-up system; set the coiling tension of the strip.
