Product Description:

1.Structure of Tin Free Steel TFS for Twist-off Caps and Crown Caps Description


Tin Free Steel (TFS) is thin black plate with two coats; one of metal chrome film and the other of chromium oxide. TFS is ideal for the manufacturing of crowns, container ends & shallow drawn cans etc. TFS is also known as Chromium coated steel.


2.Main Features of the Tin Free Steel TFS for Twist-off Caps and Crown Caps


Also known as chromed steel, tin-free steel (TFS) is obtained by coating the metal base (low-carbon steel) with an ultra-thin layer of metallic chrome and then with a chromium oxide layer.

Q:How to quickly distinguish tinplate and ordinary substrate iron?
Tinplate is tin coil, measurement of tin content?. The base plate is a plain hard rolled coil, which is relatively hard without annealing.
Q:Why do tin tins rust easily when they are opened?
Tin iron loses electrons and gets an electron redox reaction to accelerate the corrosion process
Q:What is tin plate?
Tin plate, also called tin plated steel plate, is formed by tin plating on the base material of the sheet steel. Sheet steel substrate with low carbon steel as raw material, its thickness is generally 0.1 ~ 0.4mm.Tin plate according to its tin plating process can be divided into two types, namely hot dipped tinplate and galvanized tinplate.
Q:What is the difference between food grade tinplate and ordinary chemical tinplate? What is the difference between MR material and SPCC?
Tinned food grade and non food grade. The main brands are MR and SPCC. because the meat food will be wall mounted in contact with food tin coated with two layers of yellow food, the food is yellow anti solvent, anti general acid-base, thus ensuring the safety of food packaging containing iron. The food there is no absolute security argument, now the technology has been fully capable of ensuring the safety of food containing.MR's impurity is a little more than SPCC, and the price is a little high. It's OK to use SPCC to spread two layers of food on the outside
Q:What are the advantages of tin packaging?
Mature technology and high production efficiency: the production of tinplate has a long history, has a mature skill set of production equipment with matching, high production efficiency, can meet a variety of product packaging needs.
Q:Tin and tinSince the back skin as long as tinplate will rust, so why not replace tin?
Tin, also called galvanized sheet steel, atmospheric corrosion resistance ability is strong, not afraid of the rain and wind, used for building materials, general exposure in the air. Such as color plate, color steel. Because it is hard, so it is not easy to physical erosion. If the galvanized layer off, the same will rust.Can not be used. Instead of using tin tin galvanizing vessel, it is easy to cause zinc poisoning. Zinc soluble in acid, acid resistance is poor, so the tin can not be used for beverage packaging, such as carbonated drinks and fruit juice. In addition some foods, such as aquatic products, or products such as packaging, the requirements are higher, need to use advanced professional tinplate.
Q:How to open cans
A tin can be opened, the handle is separated, and the canned fruit can be clamped by the head, and the rotating knob and the tin can be opened. Remember, when you turn the knob, you can only rotate clockwise and turn counterclockwise clockwise.
Q:Is it necessary for the two cold rolling in the process of tinplate production, such as tempering and cold rolling (also called flatness)?
This is not the standard terms, generally refers to the 2 cold rolling coil after cold rolled hardness increased after heat treatment after recrystallization to obtain greater reduction.
Q:Can tinplate be shielded?
For tinplate shielding, it is a kind of shielding material, at present 3 applications more cheap, processing is good, but the finished long-term placement of rust on the fracture surface, thus affecting the weldability, which is its only drawback. If it is placed in a short time, it will not affect weldability. Electroplating is not the best way to solve the problem. My supplier is coated with an anti rust paint on the fracture surface, and then ultrasonic cleaning is done before going on line. But I mostly use "ocean shield frame copper to make," a little expensive, but the performance is very good ^_^
Q:What is the difference between Maguchi Tetsu tinplate and galvanized board
Zinc plating on the surface of thin steel plates and steel strips by continuous hot dip plating prevents corrosion of the surface of thin steel plates and steel strips. Galvanized steel sheet and steel strip are widely used in machinery, light industry, construction, transportation, chemical industry, post and telecommunications and other industries.
