For lipp steel silo construction, we have different choice for our silo construction. As following is the main choice of the material of the lipp storage silo construction.

A, steel (including steel) classification:

1, according to the thickness of the classification: (1) sheet (2) of the plate (3) Plate (4) special plate 2, according to the production method of classification: (a) hot-rolled steel plate (2) cold-rolled steel

3, according to the classification of surface features: (1) galvanized sheet (hot galvanized plate, galvanized sheet) (2) tin plate (3) composite plate (4) color coated steel

4, according to use classification: (a) steel bridge (2) boiler plate (3) Shipbuilding steel plate (4) armor plate (5) automotive steel (6) roof plate (7) structural steel (8) electrical steel (silicon) (9) a spring plate (10) other

Second, the general and mechanical structure with steel in common Japanese brands

1, Japanese steel (JIS series) grades in ordinary structural steel is mainly composed of three parts: The first part of the said material, such as: S (Steel), said Steel, F (Ferrum), said iron; second part represents different shapes, types , purpose, such as P (Plate), said plate, T (Tube), said pipe, K (Kogu) said tool; third portion represents digital features, usually minimum tensile strength. Such as: SS400-- S represents the first steel (Steel), a second S "structured" (Structure), 400 for the lower limit tensile strength 400MPa, generally designated 400MPa tensile strength of ordinary structural steel.

2, SPHC-- first steel Steel abbreviation S, P abbreviation for plate Plate, H is the heat Heat abbreviation, C abbreviation for Commercial Commercial, said the general overall hot-rolled steel sheet and strip.

3, SPHD-- said stamping hot-rolled steel sheet and strip.

4, SPHE-- expressed deep drawing hot-rolled steel sheet and strip.

5, SPCC-- said general cold rolled carbon steel sheet and strip, equivalent to China Q195-215A grades. Where C is the third letter abbreviation Cold Cold. When the need to ensure the tensile test, plus at the end of Grade T for SPCCT.

6, SPCD-- said stamping cold rolled carbon steel sheet and strip, equivalent to China 08AL (GB / T13237-1991) quality carbon structural steel.

7, SPCE-- expressed deep drawing cold rolled carbon steel sheet and strip, equivalent to China SC1 (GB5213-2001) deep drawing steel. The need to ensure non-aging, the increase in grade at the end of N is SPCEN. Cold-rolled carbon steel sheet and strip quenched Code: annealed state A, the standard quenching of S, 1/8 hard for 8,1 / 4 hard for 4,1 / 2 Hard 2, the hard one. Surface processing code: Matte finish is D, bright finish to B. Such as SPCC-SD represents the standard conditioning, general use of cold-rolled carbon sheet matte finish. Again SPCCT-SB represents the standard conditioning, bright processing required to ensure cold-rolled carbon sheet mechanical properties.

8, JIS mechanical structural steel grades that method: S + carbon + letter code (C, CK), in which the carbon content with intermediate values ​​× 100, said the letter C: carbon K: said carburizing steel. Such as carbon structural steel coil S20C carbon content of 0.18-0.23%.

Third, China's and Japan silicon steel grades that way

1, China grades representation:

(1) cold-rolled non-oriented silicon steel strip (sheet)

Representation: DW + iron loss value (at a frequency of 50HZ, sine wave peak magnetic induction unit weight of iron loss value of 1.5T) + 100 times 100 times the thickness values​​. As DW470-50 said iron loss value 4.7w / kg, thickness of 0.5mm cold-rolled non-oriented silicon steel, is the new model is represented as 50W470.

(2) cold rolled oriented silicon steel strip (sheet)

Representation: DQ + iron loss value (at a frequency of 50HZ, sine wave peak magnetic induction unit weight of iron loss 1.7T) + 100 times 100 times the thickness values​​. Sometimes the iron loss value plus G represents a high magnetic induction. As DQ133-30 said iron loss is 1.33, thickness of 0.3mm cold rolled oriented silicon steel strip (tablets), is now the new model is represented as 30Q133.

(3) Hot-rolled silicon steel sheet hot-rolled silicon steel sheet with DR said, according to the number of silicon content into low condemnation Zheng Jun ê loquat? .8%), High silicon steel (silicon content> 2.8%). Representation: DR + iron loss value (50HZ repeatedly magnetized with a sine-shaped and the magnetic flux density changes as the unit weight of the maximum value of the iron loss when 1.5T) + 100 times 100 times thickness values​​. As the iron loss value of 5.1 indicates DR510-50 thickness of hot-rolled silicon steel sheet of 0.5mm. Household appliances, hot-rolled silicon steel sheet with grades of iron loss value by JDR + + thickness values ​​expressed as JDR540-50.

2, Japan grades representation:

(1) cold-rolled non-oriented silicon steel strip by the nominal thickness (expanded 100-fold value) + Code A + iron loss guaranteed value (the frequency 50HZ, the maximum flux density is iron loss expand to 100 times the value when after 1.5T) . Expressed as 50A470 thickness of 0.5mm, iron loss guarantee is ≤4.7 cold rolled non-oriented silicon steel belt.

(2) cold-rolled grain oriented silicon steel with a nominal thickness by (enlarged 100 times the value) + Code G: said common materials, P: indicates highly oriented material + iron loss guaranteed value (the frequency 50HZ, the maximum flux density is 1.7T measurements of the iron loss value after 100 times enlarged). Expressed as 30G130 thickness of 0.3mm, cold-rolled iron loss guarantee of oriented silicon steel strip is ≤1.3.

Four, electroplating tin plate and hot dip galvanized sheet:

1, plating tin plate tin plated steel sheet and strip, also known as tinplate, this plate (with) a tin-plated, with good corrosion resistance, and non-toxic, can be used as canned packaging materials, cables and outside sheathing, instrumentation telecommunications parts, flashlight and other hardware.

2, hot dip galvanized sheet hot dip galvanized sheet is divided into hot-rolled and cold-rolled galvanized sheet hot dip galvanized sheet, cold rolled hot galvanized plate mainly used in construction, appliance, automotive, container and furniture and other fields. Hot-rolled galvanized sheet steel is mainly used for construction, automobile manufacturing, steel silo manufacturing and other industries. The main features of the city of corrosion resistance, good surface quality, conducive to deep processing.

Five, color coated steel sheet and strip is color coated metal strip as the base, on its surface coated with various types of organic coatings products, used in construction, home appliances, steel furniture, transport and other fields.
